SOUND-REPRODUCING DEVICE.

Application filed March 21, 1923. Serial No. 626,617.

The invention relates to improvements in sound producing devices and more particularly `to such devices adapted to be positioned within a doll or toy.

The main `object of the invention is to provide a device of this character which is not only simple and eflicient in operation, but which also lends itself to easy and cheap construction. l y I Further and more specific objects, fea-tures and advantages will more clearly appear from the detail description given bel'ow taken in connection with the. accompanying sheet of dra-wings which yforms a part. of this specification. In the drawings which'illustrate apreferred embodiment of the invention:

Figure 1 is ay vert-ical Section through the housing, diaphragms and bellows, showing the valve or door in its relation to the trip mechanism. y

Figure 2 is a. plan with the cover removed.

Figure 3 is an end view of the valve and the .trip mechanism. n

Figure 4 is a modified and preferred form of a trip.

Figure 5 is a view showing the trip in its relation to a modified type of valve or door.

Figure 6 is a side view of the form shown bi Figure 5. 'A

Figizire 7 is a plan of the form shown by Figure 6. y

Referring now to the. drawings, wherein like .reference characters designate corresponding parts throughout thel several views, designates a cylindrical housing and 6 the bottom flanged closure therefore,r which may be formed separable or integral therewith as manufacturing necessities may` require. I/Vithin the housing there is provided a stationary lower diaphragm 7 which has secured thereto a. bo-ttoin plate 8, the tongues 9 of said plate extending through recesses in vthe bottom closure 6 and said tongues are bent flush with the bottom to as to rigidly secure the diaphragm 7 in position within the hous ing. A top or movable diaphragm 10 is connected tothe bottom diaphragm the normally collapsed bellows 11,itbeing Vobserved that the bottom of said bellows extend about the periphery of the diaphragm 7 so that the said bellows are clamped by the plate 8. That is, the lower edge of the b-ellows 11 as viewed in Fig. 1.; isturnedinwardly underneath the edge of the bellows head 7 andis clamped thereto by the metal disc member S, so that the inwardly turned lower edge of the bellows is clamped between flat surfaces of the head Tand disc 8 ,at the peripheries thereof. The upper edge of the bellows 12 is secured in any well-known inanner withinthe gr'ooved portion of the diaphragm orf-weighty head 10. Formed preferably integral with the diaphragm 10, I

have provided a frustro-conical extension .13

having an aperture 14: in the top thereof'and within the bot-tom of said conical member and the head 10, a cylindrical cup 15. is 'positioned which cup extends below the lsaid head 10 and within the bellows 11. A horizontal tube 16 provided with a suitable reed, provides communication betweenthe interior of the. bellows and the cup for the passage of the air that is drawn into the bellows when the same are extended. I

The conical extension 13 is provided with the band or collar 19 secured by a screw20 and hingedly connect-cdas at 21 to the band or collar. I have provided a valve, closure or door 2 2 which controls the escape of the air trapped within the bellowsgwhen the same collapse from their extended position. A lguide rod or bar 24 is securedat its lower end to the diaphragm or head 7 and extends through a recess yor aperture. centrally of the upper diaphragm or weighty head 10 so as to permit the latter to slide on x said bar when the bellows are extended andare collapsed, it being ofcourse understood that the diaphragm or plate 10 is of heavy material such as lead and consequently` when the entire device is inverted and tilted fromV one position to the other, the said diaphragm or head 10 will fall by gravity so asv to collapse the bellows and of course force the trapped air to 'escape past the valve 22.

V In the form shown by Figures 1 to 3inclusive of the drawings, the valve. 22 which is hingedly connected as at 21fto the band 19jis normallyclosefd by the spring 26, -one end ofkwhich is connected to said vband and vthe opposite end-to the `valve.- -.The said valve 22`is rectangular-and the outer' end of struck finger 29 on the kinside of the rec-css or opening 27.

Secured to the ripper end of the guide bar 24, I have provided a double tripping element, which in the form shown by the Fi gures 1 to 3, consists of a flat strip 30, the upper end of which is provided with a tongue 31, adapted to pass through an aperture 32 and bentso as to be secured on the bar. Substantially intermediate the upper and lower ends of the strip, there are provided thearms 33, 34 which are bent or wrapped about the guide bar 24, the said arm 34 having an outwardly bent prong or projection 35 which is adapted to engage the finger 29 so as to trip and to open the valve 22. I'he lower end of the strip is bent slightly outwardly and terminates in a substantially horizontal stop 37 which trips the valve 22 after the same passes the first trip above referred to. lith the parts as shown in Fig. 1, the weight 10 will drop by gravity and compress the bellows so that air will be forced out of the bellows through the reed pipe 16 causing the reed to sound and the sound therefrom will issue into the sound chamber' of the frustro-conical extension. During the first part of the collapsible movement of the bellows the valve 22 will be opened by the engagement of the finger 29 with the projection so that the sound is free to issue through the opening 14 and out of the device through the fabric covering on top thereof. As the bellows is further compressed by the weight 10 the finger 29 will slip off of the projection thus permitting the valve 22 to close the opening 14 and so terminate the sound from the reed pipe. As the bellows is further compressed by the weight 10 the outer end of the valve 22 will engage the stop or projection 37 and so cause the valve' 22 to be again op-ened whereby a second syllable will be heard from the reed pipe during the last part of the collapse of the bellows. -liVhen the bellows are fully extended, the valve 22 will be disposed slightly above the first trip 35 and since said valve is free to open, a very slight escape of the air will be effected, just befo-re the valve 22 is initially tripped. The first sound produced is that of the phonetic sound in aronouncinr the letter M whichbroadens out when the valve 22 is first tripped vquickly to the pronunciation of the letters Alm The slight interval between the first trip and the second trip also produces a sound of the letter M and when vthe valve 22 is tripped the second time, and

jection 35 owing to the beveled or slanting posit-ion of the finger 29 and the fact that the valve 22 has some side play in its pivotal connection permitting the valve to move sideways sufficiently forthe finger 29 to pass the-projection 35.

vice shown -in Figures 1 to 3 of the drawings, I have devised a very efficient manner of tripping the valve 22 by utilizing a clip designated in its entirety by numeral 38, one end of the clip 39 passing through an aperture or recess 40 in the upper end of the guide bar 24 and bent thereon. The clip eX- tends outwardly to one side of the bar and is curved as indicated at 41, which constitutes the trip and the equivalent of the tongue 35 heretofore referred to.y The opposite end of the clip extends through a recess in the bar 24 and is bent downwardly as indicated at 43 and terminates in a substantially horizontal extension 44 which is somewhat below the bent portion 41 of said clip and the said extension 44 corresponds with the portion 37, being of a length to permit of the sliding movement of the outer end of the valve 22 as the same gradually opens to effect the prolonged sound as above explained.

In Figures 5, 6, and 7 I have shown an arrangement having a still further modified valve operating arrangement wherein a tripping device or clip is bent or crimped on the bar 24 to provide a hooked end 41', said clip having a step-down portion 42a on the opposite side of the bar 24, which clip is designed for use in connection with a particular type of valve shown at45, hingedly connected in the same manner as the valve 22 above referred to. The valve 45, however, is provided with a finger 4b, which cooperates with the hook 41aL on one side of the bar 24, and an extension 47, somewhat longer in length than the finger 46 which cooperates with the step-clown portion 42a of the clip on the opposite side of the bar, the parts operating and producing the same result, namely, the double tripping of the valve to effect a variable sound simulating the cry of Ma-Ma. Certain features of the invention I havedisclosed in my copending application Ser. No. 589,290 filed September 20, 1922 (Patent 1,463,008 granted July24, 1923).
